ABSTRACT

A new miniature rose plant that has abundant, yellow-orange flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL DESIGNATION

Rosa hybrid

VARIETY DENOMINATION

‘Poulpai001’

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety ofminiature rose plant which originated from a controlled crossing betweenthe female seed parent, an unnamed seedling, and the male pollen parent‘Poulhi008’, described and illustrated U.S. Plant Pat. No 15,722.

The two parents were crossed during the summer of 2002 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulpai001’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its female seed parent by thefollowing combination of characteristics:

-   -   1. The seed parent is taller in growth height than ‘Poulpai001’.    -   2. The seed parent has lighter yellow flower coloration than        ‘Poulpai001’.

The new variety may be distinguished from its male pollen parent by thefollowing combination of characteristics:

-   -   1. The pollen parent has pink flowers, while ‘Poulpai001’ has        yellow-orange flowers.    -   2. The pollen parent has very glossy leaves, while ‘Poulpai001’        has matte leaves.

The objective of the hybridization of this rose variety for commercialculture was to create a new and distinct variety with unique qualities,such as:

-   -   1. Uniform and abundant yellow-orange flowers with old fashion        flower form;    -   2. Vigorous and compact growth;    -   3. Year-round flowering under glasshouse conditions;    -   4. Suitability for production from softwood cuttings in pots;    -   5. Durable flowers and foliage which make a variety suitable for        distribution in the floral industry.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventors, anddistinguish ‘Poulpai001’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization and conducted evaluations onthe resulting seedlings in a controlled environment in Fredensborg,Denmark. ‘Poulpai001’ was selected by the inventor as a single plantfrom the progeny of the hybridization in 2002.

Asexual reproduction of ‘Poulpai001’ by vegetative cuttings andtraditional budding was first done by Mogens N. Olesen in the nursery inFredensborg, Denmark in 2003. This initial and other subsequentpropagations conducted in controlled environments have demonstrated thatthe characteristics of ‘Poulpai001’ are true to type and are transmittedfrom one generation to the next.
